IMPROVEMENT IN HVDRANTS.

Specification forming part of Letters Patent No. 121,716, dated December 12, 1871.

To all whom it may concern:

Be it known that I, PATRICK H. GRIFFIN, of the city of Albany, State of New York, have invented certain new and useful Improvements in Hydrants; and I do hereby declare that the following is a description thereof, reference being had to the accompanying drawing forming a part of this specification, in which- Figure l represents a perspective view of the hydrant embodying my invention. Fig. 2 is a sectional elevation of the same. Fig. 3 is a vertical view of the same from above.

My invention consists in certain arrangements of elements with a hydrant, whereby the operating parts of the saine may be taken up from the ground without the ground being dug up, as is now required with hydrants in general use.

To enable others skilled in the art to make and use my invention, I will proceed to describe it in reference to the drawing and the letters of reference marked thereon, the same letters indicating like parts.

In the drawing, A represents the usual feedpipe leading from the street main to the hydrant, which feed-pipe is buried in the earth below the frost line in a proper manner. The terminating end ofthe said feed-pipe is turned up vertically',

4 and is provided with a proper coupling piece, D,

as shown in Figs. l and 2. B is the cock, placed above the feed-pipe A and connected with the duct C, which duct I denominate the crank-duct. The lower end of the said crank-duct G is provided with a screw-thread corresponding with the screw-thread on the coupling D, with which it connects. The axis ofthe said screw-cut end of the crank-duct C is made to line with the axis of the cock B so as to throw the said crank-duct outside the line of the 'axis oi' both the coupling D below and the cock B above, and cause it to intersect with the cock at one of its sides, as in Fig. 2. By this arrangement of the crank-duct C outside of the line of the axis of the cock B and couppling D the operating parts of the hydrant above the coupling can be readily attached to or detached from the said coupling by revolving the said operating parts in the proper direction. E is the key or valve operating' with the cock B to cut off or let on the flow of the water from the crank-duct C, which key is provided with the centralvertical chamber e and disch arge-port c above and receiving-port e on one side, all of which are so arranged that when the said key E is turned so as to bring the port e facing the crank-duct G the water will ow into the central vertical chamber e to escape from the discharge-port e into the discharge-pipe inserted in or connected with the said key E; and when the said port e" is turned away from the said crank-duct all iiow of the water will be cut oft". By this part of my invention the operating parts are rendered capable of being removed by simply revolving the whole in a direction which will cause the coupling to unscrew from the lower vertical end of the crank-duct. F is the discharge-pipe connecting with the key E in a secure and water-tight manner, as shown in Fig. 2. The said discharge-pipe is made of a length sufficient to reach from the cock B, below, up through the ground to any desirable height above the same. The upper end of the said discharge-pipe is curved or bent down so as to form a spout or nozzle, F', from which the water may be discharged downward. The said discharge-pipe is intended not only to act for the discharge ofthe water, but is also intended to operate as a shaft or stem to the key E of the cock, with which it is connected or attached; and when the said discharge-pipe nozzle F is turned from point .fr or z to the position of y, Fig. 3, the port e of the key E will face the duct C and permit the ow ofthe water upward; areverse movement will cut off the How. G is an arm attached to the key e or to the discharge-pipe F at the top of the cock B, as shown in Figs. 1 and 2. The said arm Gr will, when the discharge-pipe and key is turned or revolved around, be made to describe the circle shown by dotted lines in Fig. 3, (the smaller circle shown.) H is a catch attached to one side of the upper end of the cock B, as shown in the several gures, which catch is placed within the radius of the arm G attached to the key or discharge-pipe, and is intended to engage with the said arm when the arm is turned in either direction a single turn. By this arrangement of the said arm attached to the key or discharge-pipe with the stop or catch attached to the cock provided with the crank-duct, connecting, by screw-threads, with the coupling ofthe feedpipe, the operating parts of the hydrant can be unscrewed and detached from the coupling, or be firmly screwed and attached thereto, by simply revolving the discharge-pipe, acting as the stem of the key, in a proper direction. Hydrants,

as heretofore eonstrtn'ted. have not possvssvd these elements t'or attavhing' and dvtavhine thv i Operating parts t'roln thv tixvd or liurivd portions t ofthe saine without digging.: up thv varth and un- Covering' the coupling vonnvvting.;y with thv t'vvd pipe.
